Steps to Calculate GCD of 778, 338, 56, 493 using LCM Formula
Given numbers are 778, 338, 56, 493
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(778, 338) = 131482
GCD(778, 338) = ( 778 x 338 ) / 131482
= 778 / 338
= 778
Step2:
LCM(2, 56) = 56
GCD(2, 56) = ( 2 x 56 ) / 56
= 2 / 56
= 2
Step3:
LCM(2, 493) = 986
GCD(2, 493) = ( 2 x 493 ) / 986
= 2 / 493
= 2
So, Greatest Common Divisor of 778, 338, 56, 493 is 1
